UNITED STATES MARIE LOUlSE RUSSELL, OF OI-I ICAGO, ILLINOIS.

OVERFLOW-INDICATOR.

SPECIFICATION forming part of Letters Patent No. 385,825, dated July 10,1888.

(No model.)

To all whom, it may concern:

Be it known that I, hIARIE Loursn RUssELL, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented a new and useful Overflow-lndicator, of whichthe following is a specification.

My invention relates to alarms to be at tached to the overflow pipes ofwash -basins, bathtubs, cisterns, or other like articles, where it maybe desirable to inform the attendant that the water-receptacle is filledto the desired height.

The object of this invention is to give the alarm by soundiuga gongorothcr alarm which may be operated by clockwork, or by co1npleting thecircuit of an electric battery to accomplish the same purpose, and to dothis before much water has been wasted by running off through theoverflow-pipe.

In the accompanying drawings, Figure 1 is a front elevation of my deviceadapted to use with a clock-workoperated gong. Fig. 2 is a sideelevation of a portion of the same, partly in section.

The same letters of reference apply to the same parts in both figures.

A is a rectangular box or case, preferably made of sheet metal. Its foursides are closed. Its top 1 and bottom 2 are made in any desiredornamental form, and are each provided with a pipe of smaller area thanthe box A, to which they are attached. Pipe 3 is connected with theoverflow-pipe of the wash-bowl, bath-tub,

' or cistern, and pipe 4 with the drain or other receptacle.

B is a transverse horizontal shaft arranged in suitable bearings closeto one side of the box. Shaft B has a pan, 5, firmly attached to it toreceive the overflow-water. when said pan is set in position for thatpurpose. Shaft B is provided with a crank-arm, 6, on the outside of boxA.

G is a pitman having a hook, 7, at its upper end adapted to engage on aroller, 8, pivotally secured to the tail portion 9 of hammer D. Thelower end of pitman C is provided with a sleeve, 10, to fit upon thecrank-pin 11. Roller 8 is capable of rotating easily upon pin 12 on thetail 9 of the hammer.

E is a pendent rod secured at its upper end to the body of roller 8, andis provided with an adj ustablc weight, 13, which rotates upon thescrew-threaded portion 14 of rod E.

Roller Sis provided with a groove to receive the inwardly-tinned hook ornib 15 of pitman 7.

The pan 5 may be simply a flat plate, if desired, without departing fromthe spirit of my invention; but I prefer that it should be a pan to holda small quantity of water, so as not to release the alarm by the jarringoccasioned by the shutting of a door or walking across the room.

It will be seen that by raising or lowering the balance-weight 12 thescnsitivencss of the de vice may be adjusted as desired.

Instead of hammer D, a circuit-closer or electrical switch may be usedto give the alarm at any distant point.

\Vhat I claim as new, and desire to secure by Letters Patent, is
